我需要某人在这个我的出口问题上的专业知识。API导出问题
它是如何工作：选择摄像机（动画与否是可选的）>>文件>>导出>>选择文件类型：.chan（需要加载该脚本插件）
这里是哪里出了问题开始。它能够创建一个.text文件，但是，它不会'导出'或将内容写出到文本文件中，并且文件大小为零字节。
我利用当前的API，它已被编码，修改代码在一些玛雅CMDS添加
能有人好心帮我吗？

您是否认为如果我重新安排我的代码，它会有效吗？我仍然需要用户界面弹出，虽然 – dissidia 2014-10-29 02:26:48
您可能会将UI变成LayoutDialog并在创建fileExporter之前调用它，然后在创建时将收集的信息传递给FileExporter。 看起来你可以在普通的旧python脚本中完成大部分工作，而不是通过API。也许这会简化问题。 – theodox 2014-10-29 05:29:11
我想我尝试过类似的方法，但它不起作用。我认为这可能是由于API的编码方式或某些因素，因为导出在用户选择对象>>文件>>导出选择时起作用，这是一种自动化过程。 – dissidia 2014-10-29 06:39:36
